Subject: [PATCH] soc: imx: gpcv2: Use dev_err_probe() to simplify error handling
Date: Tue, 11 Aug 2020 11:04:42 +0800 [thread overview]
Message-ID: <1597115082-20328-1-git-send-email-Anson.Huang@nxp.com> (raw)
dev_err_probe() can reduce code size, uniform error handling and record the
defer probe reason etc., use it to simplify the code.
